How long does Advil (ibuprofen) typically last?
For most people, the pain- and fever-relieving effects of Advil (ibuprofen) last about 4 to 6 hours. That is why the usual adult dosing schedule is every 4 to 6 hours as needed, depending on the strength and whether it’s prescription or over-the-counter.
How long does it work for pain vs fever?
The timing is similar, but people often notice pain relief within about 30 to 60 minutes after taking a dose, with effects continuing for several hours. Fever reduction also typically starts within about an hour and then tapers off over the next several hours.
What changes how long Advil lasts?
How long it lasts can vary based on:
- Dose (higher doses generally last the full dosing window)
- The product type (regular vs extended-release)
- Whether it’s taken with food (food can slow onset, but not usually the overall duration)
- The specific problem being treated (tooth pain, muscle pain, menstrual cramps, etc.)
- Individual metabolism and kidney function
Does extended-release Advil last longer?
Yes. If you take an extended-release version, it’s designed to release medicine more slowly, so relief can last longer than standard tablets—often closer to a full-day dosing interval depending on the exact product instructions.
How often can you take it?
Follow the dosing directions on the specific bottle you have (or your clinician’s instructions). For standard (non-extended-release) ibuprofen, dosing is commonly every 4 to 6 hours as needed, but you should not exceed the daily maximum listed on the label.
When should you stop taking it or get help?
Seek medical advice urgently if you have signs of an allergic reaction (hives, swelling, trouble breathing), black or bloody stools, vomiting blood, severe stomach pain, or chest pain. Also contact a clinician if symptoms persist or worsen after a few days of self-treatment.
